Bamburgh Coast and Hills is the name given to a Site of Special Scientific Interest (SSSI) on the coast of north Northumberland, England. The site is one of the longest-standing SSSIs in England, having been listed since 1954, and displays the interaction of a fluid magma rock, now known as the Whin Sill, interacting with older sedimentary rock. Coastal erosion at the site enables sections of the geological strata to be seen. In turn, the soil associated with the Whin Sill gives rise to a distinct pattern of vegetation which on its own merits is at this site found notable.
